Small extension point difficulties

Hello,
I have had some trouble with the CCC component, but I have been able to resolve it so far.
But there are two things that I can't solve.

The y Axis title, and the x axis label.

I've got an example of what I did so far (using ccc2).

For the y Axis title, I tried the following extension points:

1. yAxisTitle: 'UV Level',
2. yAxisTitle_text: 'UV Level',
3. yAxisTitleLabel_text: 'UV Level',

with this I wanted to place a title for the yAxis.

For the x axis label I tried:

1. baseAxisScale_dateTickFormat: '%m-%d %H',
2. xAxisScale_dateTickFormat: '%m-%d %H',

to show the format '%m-%d %H' instead of '%H:%M %p' for each value of the xAxisLabel.

Thank you for your help.
